Abstract
The invention belongs to a single-phase and three-phase AC stabilized-voltage power supply employing two AC chopper circuits to adjust a compensation voltage. The power supply consists of a compensation transformer, filter capacitors, filter inductors, bidirectional electronic switches, and an adjustment control circuit, thereby forming two AC chopper circuits. The compensation transformer is connected to output ends of the two AC chopper circuits, thereby obtaining the difference between two AC voltages. Therefore, only if the reverse adjustment of the chopper break-make ratio of the two AC chopper circuits is carried out, is the compensation transformer T enabled to obtain a bidirectional compensation voltage, thereby enabling the output voltages outputted by two stabilized-voltage AC voltage output ends to be stable. Compared with an AC stabilized-voltage power supply, invented by the same inventor, employing a half-bridge AC chopper circuit to adjust compensation, the power supply employs two bidirectional electronic switches to replace an inverted-phase auto transformer, is remarkable in energy-saving effect, saves materials, is small in size, and is light in weight. Compared with two invention patents submitted last month, the power supply does not employ a plurality of bidirectional electronic switches for conversion in an adjustment process, is good in continuity, and is more reliable in work.
